Donovan makes a flathead but most guys use an OHV head. The Model D (Donovan's name for the banger block) is super strong, and expensive but worth it if you are going to drive it hard. They are not legal in V4 Bonneville classes. I'm not sure they are still in production???

The Burtz is a more economical way to get a good block/crank, they are really nice, but also not legal for Bonneville.
